Question

do a unit test for area circle c++

Answer 1

I hope that you are asking an programme to find out the area of circle in C++ so here is the solution for it.

#include <iostream>
#define PI 3.14159
using namespace std;

int main()
{
//Define radius and area
float radius, area;
//Get the user input for the radius   
cout<<" Input the radius";
cin>>radius;
//Computer the area
area = PI*(radius*radius);
cout<<" The area of the circle is : "<< area << endl;
cout << endl;
return 0;
}
